I used to be able to teleport to the wilderness events. Ever since the max cash update It no longer gives me the option from the imp / ramokee at the wilderness wall in edgeville to teleport. They just say there's an event going on... and end of chat.
Huh, they did say that they fixed it in the June 19th update. Although I haven't been able to test it out for myself since I haven't unlocked the ability to use their teleport.
But if it is still broken for you, then I would suggest you send in a bug report.
It's nice to be important, but it's more important to be nice.
